Although Time Warner does not sell modems, compatible units can be purchased through retail outlets such as Best Buy, Target and Wal-Mart, or they can be purchased online at Amazon or TigerDirect, as noted by the company's "Buy Your Modem" website page. A list of modems approved for use by Time Warner can be found at the company's website. A drop-down menu that opens from the website's home page "Support" link displays the "Buy Your Modem" option and leads to the approved list of modems.
The Time Warner "Buy Your Modem" page provides a comparison of the benefits of leasing vs. purchasing a modem. The page states that, as of 2015, most modem retail prices range between $50 and $100, and the current Time Warner leasing cost is $8 per month. The modem purchase page makes note of the technical support guarantee benefit that comes with a leasing arrangement, and also advises that the owner is responsible for a purchased modem rather than Time Warner.
The "Buy Your Modem" page provides a printer-friendly list of the approved modems and includes instructions on how to activate a purchased unit. More than 20 compatible modems are listed, and include manufacturers such as ARRIS / Motorola, Netgear, D-Link, Zoom and ZyXEL. Clicking on any of the listed modems displays an image of the unit and a link to an Adobe Acrobat PDF file of the unit's startup or user guide.
